Two major anthocyanins (cyanidin-3-glucoside and cyanidin-3-rutinoside), two phenolic acids (3- and caffeoylquinic acid) and 3 flavonols (rutin, quercetin-3-glucoside, and
quercetin-malonyl-glucoside) were identified using LC–QTOF–MS and were quantified using HPLC.
Approximately, 60–70% of the fruit anthocyanins were retained in the final juice, which also contained
high levels of caffeoylquinic acids, relative to the fruit. Mashing and pressing were the steps which were
effective for the recovery of fruit polyphenolics into the juice fraction. Moreover, anin vitro gastrointestinal digestion model, applied to determine the effect of processing on the bioavailability of mulberry
antioxidants, indicated a higher anthocyanin bioavailability for the fruit matrix than for the juice matrix.
